SWITCH.

Application ledlebruary 19, 1927. Serial No. 169,486.

My invention relates to a new and useful improvement in a switchwhich may be used for various purposes, but particularly adapted for use on electrical ranges where it is desirable that the same switch may be utilized for controlling the current to produce'varying-degrees of heat.

It is an object of the present invention to provide a switch which may be encased and so arranged and constructed that arcing will be prevented.

Another object of the invention is the provision of a switch of this class which may be very simple and easily manufactured, economical and durable in its structure, and requiring a minimum number of parts.

Another object of the invention is an improved spring method of` locking the switch in its various positions of movement, and resisting its movement to other positions.

Other objects will appear hereinafter. The invention consists in the combination and arrangement of parts hereinafter described and claimed.

The invention will be best understood by a reference to the accompanying drawings which form a part of this specification and in which,

Fig. 1 is a central longitudinalI vertical secw tional view of the invention.

Fig. 9 is a diagrammatic view of the wiring of the invention.

As shown in the drawings I provide each of the switches a compartment 14. separate housings being provided for eachof the switches, if desired. However, I have shown a housing 15 which may be elongated to ex-l tend across the front of an electrical range and provided with the compartment 14 and the compartment 16. and as many compartiis Vments as may be desired, dependent upon the number oEE switches -used with the range. A

cover 17 is mounted upon the housing so as to seal each of these compartments from each o ther, and seal from leakingso that, if des1red, each of the compartments may be filled with oil, thus immersing the mechanism of the'invention in oil so as to positively prevent arcing under all conditions.

Mounted in the compartment 14 and spaced from the bottom 18 is an insulating plate 19. Secured to this plate 19 and projecting upwardly therefrom is a spring contact 20 which is held in position by the screw 21 upon which, exterior of the housing, is mounted the contact block 22. If desired, this screw 21 may beused simply as a terminal with a suitable binding nutmounted thereon. The upper end of this contact member is doubled upon itself as at 23, the upper end being rearwardly extended ,to form the rearwardly extended portion 24, as shown in Fig. 6. Co-operating with the contact19 is a metal resilient contact 25 which y is held in position on the insulating block 19 by means of the screw 30 upon which is threaded the nut 31 which engages the metal plate 32 which is clamped by the n'ut 33 threaded on the\screw 21. A co-operating contact 34 is positioned adjacent the contact 29 and held in position bythe screw 35, 'as shown' in Fig. 5. A contact 36 is projected upwardly from the insulating plate 19 and held in position by the screw 37 which car ries the contact plug 38. A co-operating contact 39 is mounted on the screw 40 which carries the contact plug41.

.Threaded into the front'wall 42 of the housing is a bearing 4 3, through which is projected the shaft 44, the rear end of the shaftbeing journalled in a bearing 45. Fix* edly mounted upon the shaft 44 at its forward end is an operating button 46. .Fixedly mounted upon the shaft 44 within the housing is a disc 47 carrying the contact that it iits snugly between the arms 50 and 51, so that when the shaft is rotated to bring the corner of this block into engagement with the arms 50 and 51, vthe resiliency of the arms will force a quick rotation of the shaft 44 after passing center. A disc 53 is mounted on the shaft 44 fixedly and pro-l y vided on its periphery'with a4 contact 54 which embraces the periphery for a portion of its distance so that when the shaft 44 is rotated to a predetermined distance, electrical connection will be established betweenv the contacts 34 and 29. A disc 55 is fixedly mounted upon the shaft 44 and provided at its periphery with a contact member 56 which embraces its periphery for a portion of its length and serves to close electrical connection between the contacts 36 and 39 upon a rotation 'of the shaft 44 to a predetermined position. Insulating sleeves 57 'and wire 63 with the element 64. When the shaft Y tatable therewith; a metallic contact member 58 are used to space the discs apart, and a sleeve 59 spaces the disc 47 from the block 49, while a collar 60 is used to engage the y nut 61.

The location of these contact members Aon the periphery of the different discs is determine by the use to which the switch iS to be put, and in the present illustration is adapted for use with electrical ranges where various degrees of heat may be desired.

In the diagrammatic view I have illustrated the wiring commonly used with electrical ranges, land in which the employment of a multiple switch such as I have shown may be very eiiiciently utilized. In the electrical heating. elements as now used on ranges, thereis commonly employed a pair of elements which formA separate resistances but are connected, and in the drawing I have shown the element 62 connected bythe is rotated so 'asto -electrically connect the contacts 25 and 26,v the contact 56 of the disc will also electrically connect the contacts 36 and 39, this" position being illustrated at the contact 27 is connected to 9 in which the contact wire being connected tothe This will permit the delivery the lowermost diagram of Fig.

25', the feed contact 27 of the current to the wire 63 to be uniformly distributed to each of the elements 62 andQl, the current 'passing from these elements-to the und wire 66. a v

Wirgn the shaft 4 4 is further rotated, the

-limit myself to the I structure shown, but desire Asaid discs and embracing around its periph- 1,ess,asi l connection between the contacts 25 and 27 will be maintained on account of the addif tional length of the contact 48, thus through the wire 65l delivering the current to the wire 63, but only the element 62 will be connected to the gnound wir'e 66. A further rotation of the shaft 44 will electrically connect the contacts 34 and 39, these contacts being indicated in the diagrammatic view as 34 and 39', thus delivering the current through the feed wire 65 to the element 64, whence it passes through the wire 63 through the resistance or element 62 to the ground wire 66. A further rotation of the shaft 44 will break the connection between the contacts 34 and 39 and bring about the situation illustrated in the uppermost view of Fig. 9.

In this manner I have provided a multiple switch whereliy a continuous rotation of the switch will e ect the various degreesof heat as desired, by establishing the various connections illustrated.

On account of the method o f snapping the switch into' its various positions, a quick make and break is provided, and a Vrotation of Vthe switch in either direction may be effected.

It is'believed that the simplicity and durability of the structure described is apparent, and its eiiiciency has already been proven.

While I have illustrated and described the preferred form of structure I do not wish to precise form of details of to avail myself` of such variations and modifications as come within the scope of the appended claims.
